TYPEWRITER-CARRIAGE RETURN.

Specification of Letters Patent.

Patented Dec. 28, 1920.

Application led November 19, 1919. Serial No. 339,020.

To all whom it may concern:

Be it known that I, LoUIs SCHNEIDER, a citizen of the United States,residing at Clinton, in the county et Henry, State of Missouri, haveinvented a new and useful Typewriter-Carriage Return; and l do herebydeclare the following to be a lull, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to typewriter carA riage returns and has for itsobject to provide means adjacent the typewriter keys and keyboard andmounted in the liront edge of: the frame whereby the carriage may bereturned to its initial position by simply sliding a slidable membertransversely, thereby obviating the necessity of the operator raisingthe hand from the keyboard for spacing and shifting the carriage. Thisis a distinct advantage where the operator uses the touch system as itkeeps the hands practically in position over the keys oit the keyboardat all times.

A further object is to provide a carriage return and spacing meanscomprising a slidable member slidably mounted in the slot in the frontof a typewriter frame, said slidable member being spring tensioned andprovided with a pulley over which a cord passes. One end of said cord ispermanently fixed and the other end leads to and attached to thecarriage and its spacing means so that when the slidable member is movedlongitudinally the initial pull on the cord will cause a roller spacingoperation and a further pull will cause the carriage to be returned toits initial position.

lVith the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth. shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

Figure 1 is a sectional view through a p0rtion of the front frame of aconventional form of typewriter.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a perspective view of the slidable member.

Referring to the drawings, the numeral 1 designates the front extensionof a typewriter frarne which extension extends around the key board ofthe machine. The :front rail 2 is provided with a longitudinallydisposed elongated slot 3, in which slot a slidable member 4 is slidablymounted. Member 4 on its upper and lower edges is provided withlongitudinal grooves 5 which engage the inner and outer walls of thefront bar 2 and form means, whereby the member 4 will be prevented frombecoming displaced. Slidable member 4 is provided with inwardlyextending horizontally disposed spaced ears 6 between which ears apulley 74 is rotatably mounted on a pin 8. Extending around the pulley 7is a carriage operating cord 9, the end 10 of said cord extendingthrough a longitudinally disposed aperture 11 in the slidable carriageshifting member 4 and having its end secured as at 12 in the left handside of the elongated slot 3, thereby forming a stationary securingpoint Yfor the ends 10 of the cord 9. The portion 13 of the cord 9passes over a pulley 14, thence over pulleys located in any suitablemanner on the machine and has its end secured to the line space lever'of the machlne.

It is obvious that this securing means will have to be variedconsiderably according to the type of carriage and its shifting means.However, it is understood that the portion 13 of the cord 9 may be ledto the spacing and shifting mechanism of the carriage according to thetype of carriage and that any amount of leads may be used in reachingsaid spacing and shifting mechanism of the carriage. Secured to theslidable member 4 as at 15 is a coil spring 16, the other end of saidspring being secured as at 17 to the frame 1. It will be seen that asthe carriage during a writing operation'feeds t0- ward the left that apull will be imparted to the portion 13 of the cord 9 in the directionof the arrow a which will stretch the coiled spring 16, the function ofsaid coiled spring being to maintain the cord taut during a shiftingoperation or during a writing operation. During the writing operationwhen it is desired to space the roller and shift the carriage back toits initial position to the right, the finger of the operator is placedin engagement with the finger engaging member 18 of the slide 4. Thenthe slide 4 is moved in the direction of the arrow i sli/le 'will Cruisethe r which will cause a pnll'o loe impziriel `'the portion 18 oli' lieoord Y' posees over the pulley 'Y and lim ehored is at l2.
